Google map engine and Charleson donors

Although the Google map engine API is meant for businesses, there’s a lite version for non-business map geeks. I like this tool because it’s easy to embed a lot of data into the map. Here’s a quick version of the Charleston famine donors map that I’d previously made just using Google maps and dropping “pins” in places where donors were located:

All of these donations were printed in Charleston newspapers, and when I first started mapping them I was struck that (1) many of the donors printed in Charleston papers didn’t seem to live in Charleston and (2) how many of them were slaveowners.
The new map is here.
